multithreading - Write to a file from multiple threads asynchronously c#

Question

Here is my situation. I would like to make writing to the file system as efficient as possible in my application. The app is multi-threaded and each thread can possibly write to the same file. Is there a way that I can write to the file asynchronously from each thread without having the writes in the different threads bang heads together, so to speak?

I'm using C# and .NET 3.5, and I do have the Reactive Extensions installed as well.

For those who prefer code, I am using following to do remote logging from web apps...

public static class LoggingExtensions
{
    static ReaderWriterLock locker = new ReaderWriterLock();
    public static void WriteDebug(this string text)
    {
        try
        {
            locker.AcquireWriterLock(int.MaxValue); //You might wanna change timeout value 
            System.IO.File.AppendAllLines(Path.Combine(Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase).Replace("file:", ""), "debug.txt"), new[] { text });
        }
        finally
        {
            locker.ReleaseWriterLock();
        }
    }
}

Hope this saves you some time
